In this study, the genetic diversity of 12 Iranian Damask rose (Rosa damascena Mill.) genotypes was studied using amplified fragment length polymorphism (AFLP) markers. Twelve AFLP primer combinations generated 483 polymorphic bands and showed extreme variability and genetic complexity among the studied genotypes. The AFLP analysis revealed a specific amplified fragment for the genotypes collec...

Bacillus pumilus strain SAFR-032 is a non-pathogenic spore-forming bacterium exhibiting an anomalously high persistence in bactericidal environments. In its dormant state, it is capable of withstanding doses of ultraviolet (UV) radiation or hydrogen peroxide, which are lethal for the vast majority of microorganisms. This unusual resistance profile has made SAFR-032 a reference strain for studie...

The objective of the study was to estimate genetic parameters for length of productive life (LPL), and determine its genetic correlation with age at first farrowing (AFF), number of piglets weaned at first farrowing (NW), and first wean-to-insemination interval (W2I) in the Finnish Landrace swine population. Data from the Finnish national litter recording scheme were utilized to estimate the ge...

The current international standard methodology to quantify trait percent emphasis in selection indexes is based on a simple multiplication of the relative contribution each trait's economic value (converted absolute value) and its genetic deviation. This method does not reflect actual applied when index used practice. effort traits differ considerably their accuracy evaluation, no account taken...

Genetic and non-genetic correlations of the average somatic cell score (SCS) at different stages oflactation (100, 150, 200, 305 and 365 days in milk) with lactation performance were estimated based on thefirst lactation records of Iranian Holstein calving during 2000 to 2009. (Co) variance components wereestimated using derivative-free REML based on multiple traits animal models. The estimated...

BACKGROUND Schizophrenia typically onsets after puberty but is often preceded by observable childhood neurodevelopmental impairments. Whether these childhood antecedents index genetic liability is unknown. We used polygenic risk scores derived from a patient discovery sample as indicators of the genetic liability of schizophrenia. Our aim was to identify the early childhood manifestations of th...

We used the APSIM-Maize model to simulate maize potential yield (Yp) and rain-fed (Yw) when adaptation options of sowing date planting density were adopted under Representative Concentration Pathway (RCP) 4.5 8.5 in Guanzhong Plain China. The results showed that Yp would decrease by 10.6–14.9% 15.0–31.4% RCP4.5 RCP8.5 for summer maize, 13.9–19.7% 18.5–36.3% spring respectively. Yw 17.1–19.0% 23...

To clarify the genetic relationships among the Lidia breed lineages and two main Portuguese Lidia bovine populations, Casta Portuguesa and Brava dos Açores, 24 autosomal microsatellites were analyzed in 120 samples. Brava dos Açores showed the highest observed and expected heterozygosity (0.73 and 0.70, respectively) while Casta Portuguesa showed the lowest observed and expected heterozygosity ...

Data from a selection experiment for growth carried out in Brazil were analyzed in order to evaluate the direct responses on yearling weight (YW) and the correlated responses on the size and reproduction traits of cows. The experiment was started in 1976, and in 1980 three lines of Nelore cattle were established: selection (NeS), traditional (NeT), both selected for higher YW, and control (NeC)...

An experiment at the Agricultural University of Norway provided data to estimate genetic parameters of roughage intake (RI), fat-corrected milk yield (FCM), smoothed BW (SW), weight change (WC), and energy balance (EB). Weekly measurements were averaged in four consecutive 6-wk periods after parturition for each of 331 primiparous Norwegian cows of 20 sires. Amount of concentrate fed was adjust...
